COLUMN OVEN AND LIQUID CHROMATOGRAPH

摘要

A column oven includes a main unit, an auxiliary unit, an outside sensor, an internal sensor, a temperature range holding section for holding a plurality of temperature ranges, a temperature range specifying portion for specifying the temperature range to which the outside temperature belongs, a temperature control program holding section for holding a temperature control program for a control method of the main unit and the auxiliary unit in each temperature range in such a way that outputs of the main unit and the auxiliary unit are continuous in the temperature ranges that are adjacent to each other, a control method setting portion for setting a control method of the main unit and the auxiliary unit based on the temperature range specified and the temperature control program, and a temperature control portion for controlling the main unit and the auxiliary unit.

1. A column oven comprising:
a housing including inside a temperature adjusting space for accommodating an analytical column; a main unit for heating and cooling the analytical column in the temperature adjusting space; an auxiliary unit, provided separately from the main unit, for heating the analytical column in the temperature adjusting space; an outside sensor for detecting an outside temperature that is a temperature outside the housing; an internal sensor for detecting an inside temperature that is a temperature inside the temperature adjusting space; a set temperature holding section for holding a set temperature that is a target value of a temperature of the analytical column; a temperature range holding section for holding a plurality of continuous temperature ranges in a temperature scope in which the outside temperature possibly changes; a temperature range specifying portion for specifying, among the temperature ranges of the temperature range holding section, the temperature range to which the outside temperature detected by the outside sensor belongs; a temperature control program holding section for holding a temperature control program for a control method of the main unit and the auxiliary unit in each of the temperature ranges in such a way that outputs of the main unit and outputs of the auxiliary unit are continuous in the temperature ranges that are adjacent to each other; a control method setting portion for setting a control method of the main unit and the auxiliary unit based on the temperature range specified by the temperature range specifying portion and the temperature control program; and a temperature control portion for controlling the main unit and the auxiliary unit by using the control method set by the control method setting portion in such a way that the inside temperature is at the set temperature.
